Ylvis, the guys who did 'What Does The Fox Say' are comedians, so it's no surprise that they came up with this fantastic prank using a train horn, an electric car, and a lot of shocked Norwegians.

Since electric cars are almost completely silent, Ylvis could attach a set of train horns onto a Buddy EV and quietly sneak up on unsuspecting Norwegians and freak the crap out of them with the honk.

As electric cars become more and more common, expect to see this kind of huge horn/silent car prank spread. When your local high school is a blaring mess of Teslas with train horns, you'll have Ylvis to blame.
